HHeterotrophic Nutrition – What Is It And What Are Its Types? - eterotrophic nutrition is nutrition obtained by digesting organic compounds prepared by other plants or animal tissues. All animals and non-green plants cannot make their very own food ; hence they depend upon others directly or indirectly for their food supply. They‘re called heterotrophs. They break through complex compounds into simpler forms. Simply put, heterotrophs need to depend upon other sources for their survival. They lack chlorophyll and thus cannot perform photosynthesis. Essentially heterotrophic mode of nutrition is further subdivided into three groups called as : Holozoic, Saprophytic and Parasitic nutrition. A short description of those divisions is mentioned below.
1. Holozoic Nutrition :
The name of the nutrition originated from Greece where ‘holos’ means complete and ‘zoon’ stands for animal. This sort of nutrition involves consumption of food portion through mouth (opening ) . This process is known as ingestion. Once consumed, the food particles are broken down into simpler forms and also the process is termed as digestion. Finally, the vital nutrients are absorbed from the body and also the unwanted and undigested portions are eliminated. The entire process of expelling the waste material coming from the digestive tract via anus is defined as egestion. Holozoic nutrition involves all of the processes including ingestion, digestion and egestion.

2. Saprophytic Nutrition :
Again ‘Saprophytic’ is really a Greek term during which ‘sapro’ means rotten while ‘phyto’ is plants. This type of nutrition involves processing or decomposing the rotten foliage and dead or decaying organic make a difference of organisms. Saprophytes possess a tendency to gorge on dead products like wood, rotten plants, stored food to name a couple of. Some organisms that follow saprophytic nutrition are a number of fungi like mushrooms, yeasts and moulds. During this mode of nutrition, secretion of certain enzymes are released which break through complex food into simpler forms. The processed leftover will be reabsorbed from the saprophytes. This process of extracellular digestion is definitely an integral section of saprophytic nutrition. It could be best observed on Neurospora, a common bread mould or perhaps pin mould.
3. Parasitic Nutrition :
Parasitic is derived coming from the root word Parasite. ‘Para’ is really a Greek term for feeding and ‘site’ denotes grains. Parasitic nutrition is really a mode of heterotrophic nutrition where an organism (referred to as a parasite ) lives upon the body surface or within the body of another kinds of organism (referred to as a host ).
As an example, a hook-worm lives inside the intestine of humans and feeds onto it without going through the entire process of ingestion or egestion. This nutrition is viable for all those organisms that don‘t possess properly developed organs and depend upon their host’s body for deriving the nourishment. Some most typical samples of organisms following this nutrition are cuscuta, tapeworms, leeches, plasmodium, etc. Ideally, parasitic nutrition involves dwelling from the parasites inside the host’s body and feeding on the blood and intestines as their nutrition. However, sometimes the organisms position itself upon the surface from the host’s body, probably the skin and derive the nutrition, such types are called ectoparasites. Mosquitoes and leeches are the ideal samples of parasitic nutrition during which they suck out blood as nutrition coming from the host’s body surface.
Heterotrophic Nutrition – What Is It And What Are Its Types? - On the idea of heterotrophic nutrition, animals and plants happen to be classified beneath the above mentioned groups ; however these organisms could be further classified as herbivores, carnivores, omnivores and scavengers. Heterotrophic nutrition essentially differs from autotrophic nutrition. Organisms following heterotrophic nutrition are ideally referred to as consumers from the ecosystem. Unlike autotrophs, heterotrophs are dependent on others for their survival and require ready-made complex food for nutrition, sourced for them by similar organisms as other animals and plants.
